<div>
<pre>TargetInstrInfo::isTriviallyReMaterializable() doesn't check all of the
conditions on register classes and subregisters for its callers, and
reMaterialize() doesn't correctly update subregister definitions. They probably
don't have enough information to do this, but they should be extended to take
it and remove the burden from their callers.</pre>
